The sediment and heavy elements will settle tothe bottom of the reaction drum thus preventing their collection on the bottom of the outer shell. The bottom of the outer shell being thus kept .clean Willnot burn out and permit the discharge of its contents into the furnace which, if it happens, causes an explosion. The re-action drum 7 also relieves the shell 1 of part of lthe pressure :to

which the hydro-carbon is subjected by the pump 4, the pressure in said reaction ,drum being much higher than the pressurein the outer shell around said reaction drum;r The lighter elements given off in the cracking process pass through the line '11"leading through the top of the 'shell to the conventional condenser as 12.'v The heavy oil may be drained from t-he shell 1 through the outlet pipe'13controllable by a Vsuitable valve- 14. In case ythe reaction drum shouldburst the pressure in the outer shell may 'falso be relieved through said pipe 13. At intervals the re-action drum`7 maybe. cleaned 'out by rermovingl one eind thereof for that purpose.

The hydro-carbon Will be delivered into the reaction drum7 at a high.temperature and underhigh pressure. The valvelO may be closed until t-he required pressure in the reaction drum 7 isobtained and 'then slightly 'opened so as to permit the continual dis,-

charge through the'nozz'le 9 but to maint-ain thepressure in the re-action 'drum 7. The hydro-carbon Within the outer shell y1 Will be of somewhat lower temperature and lower pressure than that of the hydro-carbon in the re-action drum 7 and the vapors evolved by the release of the hydro-carbon through the nozzle 9 from higher pressure to a lower pressure Will operate 'to releasethe lighter elements or vapors from the fluid of higher pressure and t-he released vapors Will be of very high temperature and Will be distributedv through the fluid inthe outer shell and will keep such fluid in a state of constant turbulence resultingin a greater yyield of lighter elements than would be otherwise obtainable.

It often happens that `the coilbursts, on account -of the pressure Within it, and the oil in said coil, in such event is drained into the furnace causing an explosion.' To kprevent this the surrounding housing 15 has` been provided. ThishousingI consists of an enlarged tube which surrounds the coil 5, in thefurnace, andis spaced therefrom. The pipe 3, of which' the coil formed, fitted through the glands 1,6, 16,011 opposite sides of thev furnace, which close thelends of said housing.` The upper turn `of the housing y coil carries a container 17, and a fused metal is poured into' said container and fills the housing 15, and is kept in circulation by means of a vpump 18 VWhich is connected into a circulating 1ine'19, which is connected atV one end into the bottom turn of the housing coil, and at its other end into the container 17. This fused metal is thus `kept in circulatio'n about' the coil 5 Within the housing 15, and its chief purpose is to'keepsaid housing from becoming too hot, and burned out and at the same time to permit the proper heat-ing of the coil 5. AThe fused metal may be composed of lead and bismuth o`r a combination ofv other metals having a low melting point and a boilingpoint not lovver than (00 degrees F.

In case thepressru'e in the coil 5 should cause the same to burst the hydrocarbon will be retainedin the. housing 15 and Will vbe forced up into the container 17 through the fused metal and'will pass out through the relief line 20, which is cont-rolled by the relief valve 21, and conducted a sufficient distance from the thereof. 4 V

The line 20 is provided with a trap 22 in which the fused metal carried by the discharging hydrocarbon vivill collec-t and it Will drain back into the container 17 y through Vthe drain pipe 23. Y y l lnstead ofthe fused metal anyother liquid bat-h for the coil 5 may beused Which may be found to bepralctical. Y y
